A method of securely resetting a first device comprising a UICC, the method comprising providing a secure reset control application to a secure element of the UICC of the first device wherein the secure reset control application is capable of commanding the UICC to provide notification indicative of a secure reset of the first device being requested if a corresponding signal is received from a remote management server; and/or communication between the secure reset control application and a remote management server cannot be established for a predetermined period of time and upon the next first device reset, determine whether a secure reset has been requested.

Secure boot and software upgrade of a device

A method of receiving LTE data by a user device, the data being transmitted on a channel of an unlicensed band comprising the steps of receiving a cell ID from a primary LTE cell, receiving system information from the primary LTE cell for access to an unlicensed channel, receiving LTE data on the channel of an unlicensed band.

LTE transmission in unlicensed bands

A dynamic data transmission adjustment method in a wireless communication system. The system includes a base station and a user equipment. The base station and the user equipment communicate amongst themselves by using a first transmission technique. The method includes transmitting a plurality of frames between the base station and the user equipment using a regular transmission scheme according to the first transmission technique, and at least one iteration of the following steps: calculating a specific error rate in at least one specific region of the transmitted frames; and adjusting the regular transmission scheme when a value representative of the specific error rate associated to the specific region exceeds a predetermined threshold.

Dynamic data transmission adjustment method

A method and apparatus are provided for radio access technology (RAT) monitoring, in a wireless system environment having wireless communications equipment and at least two different RATs that coexist for providing to the equipment access to one or more communications networks. The equipment has at least two subsystems, each adapted for establishing and maintaining an active communications connection with a certain one of the different RATs. The equipment selects at least a first RAT, among all the RATs available in a certain geographical area, for establishing the active communications connection, according to a monitored characteristic of the first RAT. The method includes scanning a characteristic of a second RAT available for communication in the geographical area while the equipment maintains an active communications connection with the first RAT, and performing the scanning step when the equipment does not transmit signals through the active communications connection maintained with the first RAT.
